Bobcat Tree Spade

I am considering a bobcat skid steer with tracks and getting a tree spade attachment for it if there is a market for it in my area. Thoughts? Here is a link to a the sort of machine set up i'm looking for...... ..... I wont be buying the skidsteer new but may have to buy the spade new as I figure there aren't many out there, I cant find a price on the bobcat website but I'm sure its pretty pricey.

Discuss this in the forum topic anybody out there ever used a tree spade attachment?.
